How to Dial a Number
Why Does the Area Code Exist?
Area code 989 location was created to relieve pressure on the 517 areas codes as its available numbers were running out, and it became the ninth introduced in Michigan. Splitting off a new code is a standard fix telecom regulators use when a region’s population and phone-number demand outgrow the numbering capacity of an existing code. Rather than force millions of residents through a disruptive renumbering, the state carved out a new code for the northern and central portion of the old 517 territory.
The 989 and 988 Connection

When 988 was designated nationwide in 2020 as the dialing code for the National Suicide Prevention Lifeline, it created a conflict in exchanges that still allowed seven-digit local dialing.
